Advanced Search

Powerful search capabilities to find code, files, and symbols across your entire solution.

Advanced Search

Overview​

The Advanced Search feature lets you quickly find and navigate to:

  • Classes, interfaces, structs, records, and enums
  • Methods, properties, fields, and events
  • Constants and enum values
  • Namespaces and other symbols

This feature is especially valuable in large codebases where traditional file search is too slow or imprecise.

There are multiple ways to access Advanced Search:

  • Press Alt+P (default keyboard shortcut)
  • Use the Command Palette (Ctrl+Shift+P) and type "Advanced Search: Types & Symbols"
  • Click the search icon in the Solution Explorer title bar

Search Syntax​

Advanced Search offers several search modes:

To search for types (classes, interfaces, etc.), simply type the name:

Customer

This will find all types with "Customer" in their name.

To search for members within any type, use the @ syntax:

@AddItem

This will find all members named "AddItem" across all types.

To find members within a specific type, combine both approaches:

ShoppingCart@AddItem

This will find methods named "AddItem" within types named "ShoppingCart".

Constants and Enum Values​

Advanced Search can also find:

Constants​

@MaxRetryCount

This will find all constant fields named "MaxRetryCount" across your solution.

Enum Values​

OrderStatus@Pending

This will find the "Pending" value within the "OrderStatus" enum.

You can also search for enum values across all enums:

@Pending

Search Results​

The search results display:

  • Matching symbol name
  • Symbol type (class, method, property, const, enum value, etc.)
  • Containing type (for members)
  • Namespace
  • File path

To navigate to a search result:

  1. Click on the result
  2. The file will open with the cursor positioned at the symbol definition
  3. For large files, the relevant section will be automatically expanded and scrolled into view

Search Index​

The search index is automatically built when:

  • A solution is loaded
  • Project files are modified
  • The "Rebuild Search Index" command is executed

To manually rebuild the search index:

  1. Open the Command Palette (Ctrl+Shift+P)
  2. Type "C# Solution Explorer: Rebuild Search Index"
  3. Press Enter to execute the command

Tips for Effective Searching​

Quick Navigation​

  • Use partial names: typing Cust will find Customer, CustomerId, etc.
  • Case-insensitive: customer matches Customer
  • Wildcards work: *Service finds all types ending with "Service"

Finding Specific Members​

  • @Get - Find all members starting with "Get" (properties, methods)
  • @On - Find all event handlers starting with "On"
  • @_ - Find all private fields (common naming convention)

Working with Enums​

Search for specific enum values to understand their usage:

HttpStatusCode@NotFound

Or find all occurrences of a constant value:

@DefaultTimeout

Performance Tips​

  • The search index updates automatically in the background
  • First search after opening a solution might take slightly longer
  • Subsequent searches are extremely fast using the cached index
  • Index is persisted between VS Code sessions
